Description

Technical Field

[0001] The invention belongs to the technical field of artificial turf, and in particular relates to a wear-resistant and temperature-resistant artificial turf and a preparation method thereof. Background Art

[0002] Artificial turf has been significantly improved in terms of stability, turf maintenance, sliding resistance and appearance color, and is increasingly close to natural turf. Artificial turf can be divided into "sports artificial turf" and "leisure artificial turf". Sports artificial turf can be used as professional football fields, tennis courts, and golf courses, and "leisure artificial turf" can be used as garden landscaping, children's playground artificial grass, courtyard leisure artificial grass, and decorative artificial grass. Artificial turf has the characteristics of simple maintenance, low maintenance cost, durability and easy maintenance, safety and non-toxicity, elasticity, and can be used continuously around the clock. At the same time, it can solve the problem that natural turf has been trampled on for a long time and is difficult to maintain, and the required investment of manpower, material and financial resources is large.

[0003] However, the existing wear-resistant and heat-resistant artificial turf and its preparation method still have certain defects:

[0004] The density of the grass fibers after weaving is relatively sparse, and most of them are upright, which will weaken the elasticity of the lawn. The grass fibers are not firmly bonded to the backing cloth. During long-term use of the lawn, the lawn surface is easily worn, causing the grass fibers to fall off and deform, thus affecting the appearance and function of the lawn. Lawns with poor wear resistance may cause uneven surfaces, increasing the risk of falling during exercise and walking. In extreme environments, the lawn is prone to become brittle and soft, which may cause the grass fibers to break and fade, and reduce the weather resistance of the lawn. Summary of the invention

[0005] The object of the present invention is to provide a wear-resistant and temperature-resistant artificial turf and a preparation method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a wear-resistant and temperature-resistant artificial turf, comprising nylon, a back cloth material and filling particles, wherein the ratio of the components of the nylon, the back cloth material and the filling particles is 60:30:10, the back cloth material is polyvinyl chloride, the filling particles include rubber particles and silica sand, a UV stabilizer is added to the nylon, an antioxidant is coated on the nylon, and a wear-resistant coating is sprayed on the surface of the nylon.

[0007] Preferably, the UV stabilizer is a phenyl triazine, the antioxidant is a phenolic compound, and the wear-resistant coating is an acrylic material.

[0008] Preferably, the temperature is controlled at 100-150°C when the nylon and phenyl triazines are mixed, and after completion, the finished grass silk is subjected to UV irradiation test, the concentration of phenolic compounds is 0.5% to 2%, and the temperature is controlled at 100-150°C.

[0009] Preferably, the acrylic material is applied to the nylon surface by spraying or dipping, and the curing temperature is controlled between 120-180° C. and the curing time is controlled between 10-20 minutes.

[0010] Preferably, the treated grass fibers are woven into lawn fabrics by a weaving machine, the weaving density of the grass fibers is relatively high, and a layer of adhesive is applied on the back of the lawn to enhance the bonding strength between the grass fibers and the base fabric and prevent the grass fibers from falling off. After the back adhesive is applied, the lawn is subjected to a hot-pressing curing treatment to firmly bond the back adhesive to the grass fibers, thereby ensuring the durability and stability of the lawn.

[0011] Preferably, the rubber particles have a particle size of 4.0 mm and the silica sand has a particle size of 1.0 mm, which can ensure good drainage and stability of the lawn surface. The height of the grass strands can be trimmed by mechanical equipment to make the lawn more neat and beautiful.

[0012] Preferably, an anti-aging coating is applied on the surface of the lawn, the anti-aging coating is a silane compound, and the thickness of the coating is 5-10 microns to ensure effective resistance to ultraviolet rays and oxidation, but will not affect the flexibility of the grass fibers. The finished lawn is tested for wear resistance, high temperature resistance and ultraviolet resistance.

[0013] A method for preparing a wear-resistant and heat-resistant artificial turf comprises the following steps:

[0014] Step 1: Select grass fiber material nylon, backing cloth material and filling material, mix the three together, and wash and dry the grass fiber to remove surface impurities;

[0015] Step 2: Distribute the UV stabilizer and antioxidant evenly on the surface of the grass fiber by coating, and heat the grass fiber coated with the UV stabilizer to a certain temperature by hot air treatment, so that the absorber and the grass fiber are fully combined to ensure the stability of the UV protection layer;

[0016] Step 3: Use spraying to evenly coat the wear-resistant coating on the surface of the grass fiber. After the coating is completed, heat it at 120-180℃ to solidify it so that the coating is firmly combined with the grass fiber. The grass fiber is combined with the backing cloth through high-density knitting. The shape of the grass silk is curved.

[0017] Step 4: Then a layer of adhesive glue needs to be applied on the back of the lawn fabric to fix the connection between the grass fiber and the backing cloth. After applying the backing glue, the lawn will be cured by hot pressing to ensure a strong bond between the grass fiber and the backing cloth, and filler particles will be added between the surface of the lawn and the grass fibers;

[0018] Step 5: Use equipment to trim the height of the grass strands, then apply an anti-aging coating on the surface of the lawn, and conduct a wear resistance test on the finished lawn to simulate the wear of the lawn after long-term use. By exposing the lawn to a high temperature environment, observe its deformation, fading and brittleness, and use ultraviolet accelerated aging equipment to test the lawn to ensure that it still maintains good performance and appearance under long-term ultraviolet radiation.

[0019] The beneficial effects of the present invention are as follows:

[0020] The invention enhances the weather resistance of grass fiber by setting UV stabilizer, antioxidant and wear-resistant coating, and the antioxidant prevents the grass fiber from oxidative degradation in a hot environment and increases its wear resistance, thereby extending the service life of the artificial turf; high-density knitting is selected for the grass fiber to enhance the durability of the turf; the shape of the grass silk weaving is set to be curved, and the curved grass silk can imitate the appearance of real grass and enhance the elasticity of the turf; the glue applied on the back of the turf fabric is polyurethane, which has high temperature resistance and weather resistance; the subsequent hot pressing curing treatment ensures the strong combination of the grass fiber and the back cloth, thereby enhancing the wear resistance and stability of the turf; the rubber particles and silica sand can not only improve the comfort and elasticity of the turf, but also increase the stability of the grass silk, and avoid excessive bending and falling of the grass silk; the rubber particles also have good compression resistance and are suitable for sports venues; the filling particles need to be evenly spread on the surface of the turf to ensure the flatness and stability of the turf; the anti-aging coating coated on the surface of the turf can effectively delay the aging process of the turf under high temperature and sunlight exposure.
